Review your knowledge of ellipse equations and their features: center, radii, and foci.

What is the standard equation of an ellipse?

(xh)2a2+(yk)2b2=1\dfrac{(x-h)^2}{a^2}+\dfrac{(y-k)^2}{b^2}=1
This is the standard equation of the ellipse centered at (h,k)(h,k), whose horizontal radius is aa and vertical radius is bb.
